Erickson, Rockford, Ill., ,assignor to American Y Cabinet Hardware Corporation, Rockford, il., a corporation of Illinois Applicatin July .13., 1955, Serial N0. 521,821 7 Claims. 292-462) '.lihis invention vrelates .to an operator for opening a window with a swinging sash such as in a vso-called awning window in .which .the sash .swings-on the window frame ,about a horizontal artis. More particularly, the invention vformed by two parts .pivoted together and arranged so that y swinging the Vouter part out of alinement with the .innerpart automatically cams the sash to the fully closed position.

A more detailed object is to arrange I,the operator and the .guide so `that the outer part of the operator is fulcrumed on the guide as it Vis swung relative to theinner part .and acts as a leyer in bringing the sash to the closed position.

Another object is to utilize the outer operatory part again as a lever -as it is returned to alinement with the inner part to initiate opening of the sash and thereby effect the v opening.movement easily even if the sash should bind.

O ther objects and advantages of the invention will llfqecome apparent from the following detailed description iakcn ,in connection with thc accompanying drawings, in which Figure 1 vis a perspective view of 'a 'window embodying an operator which is constructed lin accordance with the present invention. Y

JFig. 6 'is an exjrfl'oded Yfragmentary perspective view ,of the operator and aportionofth'e guide. v

Fig. 7 is a perspective View of vanother portion of the guide.

As shown in the drawings for purposes of illustration, lthe invention is embodiedin a window ycomprising a rectangular frame 110 and one or more sashes '11 yclosing an'opening `12 in the frame. ln the present instance, there are-'three sashes and V'eac'h is mounted on the frame to swing about a horizontal axis which extends along the upper .edge of the sash. The latter yis lopened by pushing outwardly .on its :lower edge thus swinging Vthe sash yabout this axis.

To open the lower sash, an elongated .operator 13 is :secured at one end .to vthe lower yedge of rthe sash and is guided by a member 14 ffcr cndwiscmcvcmcnt along a I.path perpendicular tothe opening 12. T he operator is secured lto the sash 'by a plate 15KA (Fig. f6.) which is fas- 2 tened to the sash by screws 16'and is pivotally connected to the end vof the operator b ya horizontal hinge 17.

The guide 14 is secured to the sill ofthe frame 10 and is formed by a -ilat plate 18 (Fig. -6) vv vhich is fastened to the sill by screws and lhas upturned flanges 19 Vat its cndS- An invcrtcd Uchapcd -picccv20 (Fis. 7) is disposed on top of the plate and -is .formed .with lugs 21 which project downwardly into Yholes 2 2 in `the plate to lock the two parts together. At veach end of the piece ,20, the anges 19 are .cut awa-y as yshown in Fig. 6 so thatthe piece and the plate l-cooperate `to yform a tubular chan- 1.1c1123 with .thc piece dciining thc top -wall 2d and 4the side walls 25 -of the channel. The operatorv 13 slides 'endwisc Vin this .charincl .and thus Vis guided .for movement normal to the opening v 12. .Projecting laterally from the Sidc Weils ai thc Oufcr cdd ciihcpiccc :.20 are short danses 26 which-overlap .thevtlanges 19.

Hcrcili thc Qpcratcr 13 fis icintcd, that is, it :is formed by two parts 27 and 28 pivotally connected together, .so that, when `the sash is closed, the o uterpart 227 ,may be jswung out of alii-rement with the inner lpart 28 `as shown yin 4. VIn this position, the outer part .fis disposed behind the guide so that it is out of -the way land lalso prevents .the operatorfrom being moved, thereby .locking the sash 11fclo sed The inner part 28 may be a ShOItbar with one end Vhinged to the-plate 15j. The other en d of thc bar is b ifufcdicd andfihc two spaced portions f2i9 (Fig. 6) of this end .receive between vthem one enjd portion of .the outer `part t27 which may be instheform of an elongated link. YThe rover-lapping 4en d portions of the kbar anjd the linkare connected bya .pivot pin 30 so that the link 27 .may be swungrelativeto .thebar gfabout an upright axis a defined by the pin.

In accordance with the present-invention, the .operator 13 vis arranged in a novel manner .to facilitate the nal closing of rthe lsash 1,1 Iand, -at the same time, 'to insure that vthe sash is full-y closed. T o ythese ends, the outer part 27 `cooperates with .an element lrigid Withthe guide 14 to cam the .sash .to 4.the. closed position as this -part iis swung out of alinement with the inner part-2 8. Herein, this is achieved by employing the element -as Laful :r1,1m `for the 1i n k27 whereby the latter acts as a vlever-:for moving the ,pivot-3.9 away-frornthe window vt; per 1ing,12. Such movement of .the ,pivot vslides @theibar 2 8 A,and ythe feuidc .and draws thc sich clcscd- While the fulcrum element may be 'any part which is rigid with the frame 1i), it is preferred to utilize-apart of the guide 14, in ,this case `one ref ithe small flanges `26 4on thelpiece 20, for purpose. As shown :in Fig. 14, the pivot 30 .is disposed along the vbar 28 Yin Zsuch a .posivtion that .the sash 11 isfully closed when the link 27 is yturned yat rightangles .to A,the bar and abuts against the back of the guide. When the sash is short of the closed position, the Vpivot'is disposed withinthe ychannel -23 (see Fig. 3).v Thus, .asthelinkis swung laterally out-ofalinement with the bar, fone edge o f the link'abuts againstgone of the .flanges 26. Upon continued swinging, the link vis fulcrumed on this ilange and, as a result, the pivot -is movedback out yof the channel so vthat the sashfis drawn closed. i

Preferably, a Astop 31 'is employed to indicate to :the person closing the lwindow 'that the operator 153 .-is .in the lproper position for 'the .link 27 ltobe `swung in behind-the guide lil. As shown in Fig. 3, this position Vis when the pivot axis a is substantially 4alined with the end of the guide. The stop may, as shown in the drawings, be one `leg of an L-shaped bar v32 whose `other leg 33 is disposed between the operator and the plate 18 andis riveted to the latter. The leg 31 v'is spaced behind-the guide 1 4 where it is zengaged b y .aspin 35i projecting Vdowrwi/ ardly frcimthe 1 ink27 adjace'nt'the pivot 3 0. {Il ius, the lend wis'e 'sliding o f ,the` operator in the guideiis .stopped when 3 the sash is just short of the closed position as illustrated in Fig. 3. At this time, the link is swung out of alinement with the bar to complete the closing of the sash as described above. The end of the link is rounded so that it clears the side walls 25 of the guide upon such swinging.

According to another aspect of the invention, the link 27 also is utilized as a lever for initiating the opening of the sash 11 so that the sash may easily be moved away from the closed position even if it should stick in the frame 10. For this purpose, the link again is fulcrumed on the guide as it is swung back into alinement with the bar and, upon such swinging, the pivot 3! and hence the bar 28 is moved forward in the guide thereby opening the sash. In this instance, the fulcrum is formed by the pin 34 abutting against the leg or stop 31. In other words, the link first is swung away from the position shown in Fig. 4 to a position shown in Fig. 5 in which the pin first engages the leg. Upon continued turning, the leg is fulcrumed on the pin and the latter slides along the leg 31y until the link again is in alinement with the bar 28 and the sash is initially opened as illustrated in Fig. 3.

As seen in Fig. 3, the pin 34 abuts the laterally facing surface 33a of the leg 33 when the link 27 is alined with the bar 2S. Thus, as the link is swung out to open the window, that is, from the position in Fig. 4 to the position in Fig. 3, the pin abuts against this surface which thereby positions the link to slide through the guide 14. A It will be observed that, with an operator constructed in accordance with the invention, the sash 11 is locked in the closed position by swinging the link 27 in behind the guide 14 and, as an incident to this swinging, the sash is drawn tightly into the closed position. Also, returning the link into alinement with a bar 28 initiates opening of the sash and overcomes any sticking or binding so that the sash may easily be opened.
